GPM Mission
The 2013 AGU Fall Meeting, 9-13 December 2013, San Francisco, included five sessions devoted to GPM science, validation, and applications, with a total of 32 oral presentations and 48 posters.  This meeting provided a key opportunity for the precipitation community to report to the larger science community on the state of global precipitation observations and plans for exploiting observations by GPM's more-capable instruments: a Dual-frequency Precipitation Radar and the GPM Microwave Imager.

The second in-person meeting of the study group focused on defining a future clouds and precipitation satellite mission was held on 11 December 2013 in conjunction with the 2013 AGU Fall Meeting. Participants are drawn from the GPM Science Team and the ACE Study Team, JPL, universities, GSFC and beyond. The meeting had about 12 in-person participants and a similar number of teleconference participants.  Drafts of science questions, instrument concepts, orbital parameters and assignments for developing a white paper were reviewed.


Significant Planned Events


External Interactions (HQ, universities, other Gov't organizations, etc.

The Applied Remote Sensing Training (ARSET) program (Ana Prados, project lead, Code 614) conducted a three day training entitled "Introduction to the Use of Satellite Products for Air Quality Applications" in Albany, New York from November 19th through the 21st. The training was co-sponsored by the Northeast States for Coordinated Air Use Management (NESCAUM).  The event was attended by 23 staff from air quality agencies in Maine, Rhode Island, New Hampshire, New York, Pennsylvania, New Jersey and North Carolina. The course covered data access and use of satellite products from several NASA/NOAA instruments including MODIS, Calipso, and VIIRS, and how to use air quality applications web tools such as Giovanni (GSFC/GES DISC) , NOAA's IDEA website,  and the Exceptional Event Decision Support Tool at the University of Washington, which was developed with NASA funds.  The Instructors for this event were Richard Kleidman (Code 613) and Pawan Gupta (Code 614).

Seven members of Code 612 attended the 2013 Fall AGU meeting this week and presented multiple papers and posters.

Many 613 Lab members are attending the AGU Fall Meeting, San Francisco, CA, December 9-13.  In addition to oral and poster presentations, the following are convening sessions:

Ralph Kahn is convening and Robert Levy (613) is co-chairing the session entitled "Multi-sensor and Model Aerosol Data Synergy for Climate and Air Quality Applications" which will be composed of one poster session (A43D) and two oral sessions (A51L and A53K).

Leigh Munchak (613) is co-chairing a session entitled "Recent advances in polarimetric observations of aerosols, clouds and earth's surface".

Charles Ichoku is co-convener and co-chair of the session entitled "Environmental, Hydrologic, and Climatic Processes in Africa and the Mediterranean Basin I" (Oral session) and, "Environmental, Hydrologic, and Climatic Processes in Africa and the Mediterranean Basin II (Poster session)".  In addition, he will hold the annual workshop for the IDS project “Interactions and feedbacks between biomass burning and water cycle dynamics in the Northern sub-Saharan African region”.

Li, C. (614/ESSIC), J. Joiner (614), N. A. Krotkov (614), P. K. Bhartia (614) (2013), A fast and sensitive new satellite SO2 retrieval algorithm based on principal component analysis: Application to the Ozone Monitoring Instrument, Geophysical Research Letters, doi:10.1002/2013GL058134, in press.


In this paper we describe an innovative approach that can significantly reduce noise and biases in OMI SO2 retrievals compared with the operational algorithm. It is also much faster than comparable methods that rely on on-line radiative transfer calculations. It can be easily applied to other satellite sensors such as NPP OMPS to ensure continuity in long-term SO2 data records for climate and air quality research.


Accepted for Publication in Atmospheric Measurement Technqiues, Propagation of radiosonde pressure sensor errors to ozonesonde measurements by R M Stauffer (Penn State), G A Morris (Valparaiso Univ), A M Thompson (NASA-GSFC/614), E Joseph (Howard Univ), J G R Coetzee (South African Weather Service), N R Nalli (NOAA)

Whenever an ozonesonde is launched it is coupled to a radiosonde.  Since the routine deployment of radiosondes with GPS systems for locating altitude or pressure, it has been found that certain brands of radiosondes display a difference between the pressure determined with the radiosonde and with the GPS.  Because an erroneous pressure propagates to the ozonesonde measurement (the latter is the ratio between a partial pressure recorded by the ozonesonde and the total pressure from the radiosonde) it is important to assess the various radiosonde instruments used with ozonesondes to see if there are systematic differences.  We analyzed approximately 500 radiosondes of two manufacturers (5 “models”) from about 5 field campaigns or on-going monitoring sites, from the southern hemisphere subtropics to northern mid-latitudes, were analyzed.  The RS-92 showed negligible offset between the pressure and GPS pressure readings.  However, deviations were pronounced for the RS-80, which was flown with an ‘external’ GPS, and for all IMet sondes (standard, P-series, S-series).  When the radiosonde offsets were propagated to ozone readings, about 1/3 of the sondes analyzed displayed > 5% error at 26 hPa.  Column-integrated with a climatological above-burst column the differences were usually < 1%. 


Nickolay Krotkov (614) and Lok Lamsal (GESTAR and 614) are co-authors of paper  Spatially and seasonally resolved estimate of the ratio of organic matter to organic carbon, accepted for publication in Atmospheric Environment.  Particulate organic matter (OM) is of interest for air quality and climate research, but the relationship between ambient OM and organic carbon (OC) remains uncertain.  The paper combines satellite NO2 measurements from Aura Ozone Monitoring Instrument and aerosol Mass Spectrometer measurements to indirectly infer particulate Organic Matter to Organic carbon (OM/OC) ratio.


Sarah Strode (614) and Steven Pawson (610.1) published the following paper in JGR Atmospheres:  Strode, S. A., and S. Pawson (2013), Detection of carbon monoxide trends in the presence of interannual variability, J. Geophys. Res. Atmos., 118, 12,25712,273, doi:10.1002/2013JD020258.


This paper examines the timescales for detecting trends in carbon monoxide due to possible future changes in anthropogenic emissions from Asia.  We use a model simulation to estimate the impact of a given emission trend, and compare this change to the modeled and observed interannual variability in different regions of the atmosphere.  Using this approach, we identify regions where anthropogenic trends in CO may be rapidly detected by satellite or surface observations.
